Fig. 4: Potential dependency of the Li-mediated nitrogen reduction performance.
From: The Effect of Applied Potential on the Li-mediated Nitrogen Reduction Reaction Performance
a Chronoamperometry measurements using 2 M LiTFSI (with 0.1 M EtOH) as electrolyte. b Effect of the Ewe on the RNH3 and the FENH3 with 2 M LiTFSI. c Photographs of the 2 M LiTFSI electrolyte solutions post-measurement. d Photographs of different Cu electrodes with and without a SEI layer and the Pt anodes post-measurement. The black scale bar indicates a 2 mm length. e, f are analogous to (a, b) but with 1 M LiTFSI as electrolyte. All measurements were conducted at 20 bar N2 pressure and room temperature. The error bars represent the mean ± standard deviation derived from two independent measurements.
